Solution
The correct option is A Symbiosis Biologically, mycorrhiza is defined as an association of fungi and roots of vascular plants. In a mycorrhizal association, the fungus tends to colonise the host plant roots either intracellular or extracellular. However, this is a symbiotic association, which is generally mutualistic and rarely pathogenic.
